Yo:
Nobody really wants to use an Office suite other than MS Office; nobody wants to waste time using a professional photo editor other than Adobe Photoshop. Nobody wants to have to use audio-comm software other than Ventrilo/Teamspeak. Nobody wants to waste time tinkering with patches, libraries and system settings in order to get
industry standard software to work on a platform.
Distributing a userspace without support for the
applications that people
are interested in using will keep you in the background forever.
Switching costs include not only monetary or temporal setbacks, but they include the amount of "care" needed on the part of the user to make the solution appealing. If the user has to "care" too much about various aspects that don't really affect the price of gas, then there is an extra switching cost bundled with your software.
You can consider it a form of soft lock-in, where "complacency" and "inertia" will enable a user to begin to appreciate things that are familiar simply because of the familiarity, and even if something new is interesting, useful or an improvement, if it does not also support the current paradigm, it can be pushed aside as "not actually worth the stress".
Having "a word processor" is not the same as "having support for the suite of MS Office applications out of the box", and your word processor will be looked at as an "innovative idea that shows the strengths of <NEW-OS>", and shows that "big names aren't everything!", but overall it'll be seen as a toy and part of your "demonstration". Until they can open Microsoft Word, to most users all they see is "a cool new OS" with "great potential".
When they first open MS Word on the other hand, suddenly it becomes "a really smooth working environment" that "seamlessly integrates with powerful applications from multiple vendors" to manage your files and "crucial data". Is this not how people write? Isn't this how things are critiqued? It's not about having applications for every need. It's about having support for the most used applications in every category.
"Oh, look at this new OS here...it's so cute :3"
